Solution Overview

Problem

Natural baits are inconvenient to obtain and single-use, while artificial baits struggle to mimic natural movements and are difficult to detect on sonar, making fishing less effective.

Innovation Solution

An artificial bait with a dense head portion, adjustable sink rate, and retrieval vibrations, featuring a balanced design and high-density materials to enhance movement and sonar readability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If artificial bait is made of plastic or rubber material to be reusable, then durability is improved, but natural movement replication deteriorates

Engineering Contradiction:
ImprovedurabilityVSAvoidnatural movement replication
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The bait is divided into multiple segments or joints that can move relative to each other, allowing the artificial bait to replicate natural movement patterns while maintaining the durability of synthetic materials. The segmented structure enables independent movement of different body parts.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The bait incorporates dynamic elements such as flexible joints, movable appendages, or spring-loaded components that allow it to move naturally in response to water currents and retrieval motion, transforming a static plastic structure into a dynamically responsive lure.

Inventive Principle:
Principle #15Dynamics

2Ease of manufacture

If conventional artificial bait design is used, then ease of manufacture is improved, but sonar detectability deteriorates

Engineering Contradiction:
Improveease of manufactureVSAvoidsonar detectability
Core Design Contradiction:
Ease of manufactureVSDifficulty of detecting and measuring

Solution Approach 1:

The bait incorporates sonar-reflective surfaces or materials that change the acoustic signature of the lure, making it more visible to fish using sonar. This may include reflective coatings, textured surfaces, or embedded elements that bounce sonar waves back to the fish's detectors.

Inventive Principle:
Principle #32Color changes

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The bait provides controlled placement and action in water, allowing anglers to locate and manipulate its position effectively using sonar, enhancing fishing efficiency.

Implementation Method 1

The head portion can include a portion of dense material therein

Methodology Applied
Scientific EffectDensity:

Implementation Method 2

The bait described herein can be particularly advantageous when used with sonar. The aforementioned aspects allow the bait to remain forward-facing in the water, where it can easily be picked up by sonar techniques due to the lead present in the head portion of the bait.

Methodology Applied
Scientific EffectSonar: Sonar

Implementation Method 3

The bait shape including its arching back, the location of a pull point, and/or the relative density of portions of the bait contribute to these advantageous aspects of the bait.

Methodology Applied
Scientific EffectBuoyancy: Archimedes' Principle (Buoyancy)

Implementation Method 4

The head portion can include a portion of dense material therein

Methodology Applied
Scientific EffectGravity: Gravitation

Implementation Method 5

The present invention relates generally to an artificial bait (lure) that may provide erratic darting action, an adjustable sink rate, and retrieval vibrations

Methodology Applied
Scientific EffectVibration: Vibration

AI summary

The present disclosure relates to an artificial bait having certain physical characteristics that allow for it to remain forward-facing in the water to be quickly detected location- and direction-wise using sonar techniques. The characteristics of the bait also allow for it to engage in erratic darting action and remain in the water during retrieval for an extended period of time. Typically, the bait can include a body having a head portion, a tail portion, and a middle portion therebetween. A first attachment structure configured to receive a line can be located on or near the head portion. A hook structure can be inserted behind the first attachment structure, for example, on or near the middle portion of the body. The head portion can further include a portion of dense material therein.
